Protection from a player is a new variant of the protection ability. It means the following: — True-Name Nemesis can’t be the target of spells or abilities controlled by the chosen player. — True-Name Nemesis can’t be enchanted by Auras or equipped by Equipment controlled by the chosen player. (The same is true for Fortifications controlled by the chosen player, if True-Name Nemesis becomes a land.) — True-Name Nemesis can’t be blocked by creatures controlled by the chosen player. — All damage that would be dealt to True-Name Nemesis by sources controlled by the chosen player is prevented. (The same is true for sources owned by the chosen player that don’t have controllers.)
